IMPROVEMENT IN PAPER-MAKING MACHINES.

To ALL WHCM IT MAY CCNCERN;

Be it known that I, ISAAC JENNINGS, of Fairfield, in the county of `Faireld, and State of Connecticut, have invented a new and useful Improvement in Paper-Machines; andy I do hereby declarethat the following is a full, clear, and exact description'thereof, which will enable others skilled in the art to make and use thesame,

reference being had to the accompanying drawings, forming part of' this specification.

Figure 1 is an end view of a system of rollers illustrating my improvement.

Figure 2 is a side view of oneof the rollers detached..

Figure 3 is a cross-section of the same, taken through the line y y, fig. 2.

Figure 4 is a longitudinal section of the same, taken through the line :l: z, fig. 3.

Similar letters of reference indicate corresponding parts.

My invention has for its lobject to so improve the construction of ordinary paper-machines, that the paper may be removed from the rollers in the form of tubes, either straight or tapering, for-thc formation of the bodies of buckets, barrels, Ste., or to form pipes or tubing. v

And it consists in so forming the rollers that the paper tube when formed upon the rollers, may be removed therefrom without cutting or slitting the paper, as is necessary when the rollers are formed in the ordinary manner.

A is a frame, having four arms projecting at right anglesfrom each other, as shown in iig. 1. The ends of the arms of the frame A are slotted to receive the journals ofthe rollers B, which said journals are kept in place by pins C passing throughthe said slotted ends of the said arms. a are journals attached to the centres 'of 'the two frames A, and which revolve in'suitablc supports attached to the paper-machine. In the side of cach of the rollers B is formed a deep dove-tailed tapering or wedge-shaped groove, `which is lled with two Wedge` shaped-blocks b b2. The outer block b1 is so formed that its outer side may conform to the form of the roller when both blocks are in place.

This system of rollers is designed to take the place of the single roller that receives the pulp upon the ordinary machine.

In using the rollers, the framesA stand in the position shown in g. 1, the lower roller receiving the pulp. When the formation of the paper upon the lower roller is completed, the pins C, which confine its journalsin the slotted arms of the frames A, are removed, and the said frames are revolved one-quarter around, bringing the nextroller into position to receive the pulp. As the saidnframes A move forward in revolving, the journals of the roller upon which the paperbas been formed pass out of the slots in the arms ofthe frames A, the said roller passing upon a narrowy table or apron prepared to receive it.

The inner block or wedge b2 is then removed, allowing the outer block or wedge l to drop into the bottom of the'groo've, from whichit can then bevrcadily removed. This diminishes the size oftheroller so much that the hands or ringcrs of theoperator may be placed in the `groove of the roller, and passed around said roller, loosening the paper tube, so that it may be readily removed from the said roller. The blocks Zzland b2 are arranged in place, the roller returned to its place in the slotted arms of the frames A, and the pins C replaced.

'lhe next roller is then operated upon in the same manner, and so on continuously, the paper being formed uponone roller while the 'tube is being removed from the roller preceding it, soA that there is no occasion for stopping the machine. The rollers B may be made straight or tapering, as may be desired, according to the particular purpose for which the paper tubing may be intended. Thesize of the` roller may be diminished tc facilitate the removal of the paper tubing in various ways, as for instance, by drawing inward towards its centre parts from diierent sides of said roller at the same time, by an arrangcmentvof arms and levers, or in various othe'r.ways, but I prefer the manner first described, as being simple, easily operated, and notlliable to get out of order. I

I claim as new, anddesirc to secure by Letters Patent- 1. Diminishing the size of the roller after the paper has been formed in any convenient manner, so as t0 'admit of the papers being removed without cutting, substantially as and for the purpose| herein set forth and described.

2. 'The system of rollers B, constructed and arranged substantially as'hereinr shown and described, when used in connection with the other parts of a paper-machine, in place. of the ordinary single roller, 'as and for the purpose set forth. I I

The above specification of my invention signed by me, this 31st day of March, 1868.
